IMPROVED BRUSH.

a longitudinal sectional view of my improved brush.

My invent-ion consists in a brush, the handle and bristles of which areunited by a cap or band, composed of India rubber, guttapercha, or anyother suitable material or composition capable of assuming a plasticstate and of being afterward hardened, when said cap or band, in whichthe bristles are imbedded, not only encompasses and surmounts the innerends of the bristles, but forms an internal packing or binding to themas inserted in a bunch, and receives the inner end of the handle in orthrough it, under such a construction of the parts as establishes lockof said handle, and a firm union of the handle, bristles, and cap,without the use of a perforated plate for the separate insertion of thebristles in tufts, and whereby a neat, light, cheap, and durable brushis produced, constitutinga new article of manufacture.

Referring to the accompanying drawing, which represents a dust orpainters brush, but the invention is also applicable to other kinds ofbrushes A is the handle, formed, at or near its inner end, with a swellor collar, a, and with a protruding portion, I), preferably of tapershape, to enter within an inner ring, B, or binding to the bristles O,as the latter are imbedded or made to project, at their inner ends, inthe form of a bunch, within the outer band or cap D, that is made toencompass and surmount the inner ends of the bristles, and to incloseand form an outer lock or binding to the handle at its inner end.

The outer band or cap D and inner ring portion B are madeof lndiarubber, gutta-percha,or other suitable material or composition capableof assuming a plastic state, and of being afterward hardened, whichaffords every'facility for insertion of the bristles, and, by the fit ofthe parts as shown and described, secures the bristlesagainst'extraction, and firmly unites in a solid mass, as it were,'thehandle, bristles, and cap,

with an interior support to the bristles as arranged in a bunch withinthe cap.

Various means may be employed for making this improved brush, but it ispreferred to produce the sameby or through the agency of a press,operating in conjunction with a divided box and conical-shaped wedge, asfollows, thus:

'lhe bristles are temporarily tied together in a bunch, and passeddownwardly through a divided box, arranged in the bed of the press, tilltheir upper edges project sufliciently below the top of the box, thatmay be enlarged at itsnpper portion to receive within it, and around theupper ends of the bristles, a gutta-percha ring.

A conically-shaped wedge is then driven down the center of the bunch ofbristles, to give to them, after its extraction, a spread form, and tomake way for the inner ring B of gutta-percha, which is slipped to itsplace within the bristles, and made to rest on top of the conical wedge.

Au irregular lump 0fgutt-a-percha,-in a plastic state, and open at itscenter, is then laid on top of the bristles, and a follower, constructedto carry the'handle through it, and so that the inner end of the handleprojects below it, brought down and made to enter the box, and caused tocompress into a united mass the outer ring and lump, after which themass forming the cap and inner ring holding the brush is vulcanized, andthe box subsequently opened and conical wedge drawn out.

This mode of mnnufacture I make the subject of a separate applicationfor Letters Patent.

Having thus described my invention,

I claim, as a new article of manufacture- A brush, composed of an outerband or cap, D, and

'inner ring or binding B, both of soft or plastic material capahle ofbeing hardened, a handle, A, made to project at its inner end within orthrough the cap, and bristles 0, arranged in the form of a bunch, andsupported externally and internally where the same are united with thehandle, substantially as specified.
